Be it known that I, ELIJAH 1. Pnacoorc, a citizen of the United States, residing in Chi cage, county of Cook, and State of Illinois, haveinvented certain new and useful Improvements in Machines for Making Check-Row fire, of which the following is a specification.

This invention relates to check-rmwwire.

machines for forming check-row wire of that class in which the wire is automatically severed into regular lengths, and theseiengths then connected together by links or eyes form ed at the ends of the wires, which latter at their terminals are coiled back of their connected eyes or links, so as to 'form checks or shoulders at intervals along a practically continuous wire.

The general plan upon which I have designed my machine to operate is to sever the wire into lengths, bend these lengths into hook shape at theirends, connect these hooks in pairs, and coil the free ends of the hooks around the wires,so as to form in a practically continuous wire pairs of connected eyeswiih checks or shoulders back of the same.

The features of my invention are hereinafter described and claimed, and illustrated in the annexed drawings, in which- Figurel is aside elevation with portions of the machine broken away at each end thereof. Fig. 2 is a top plan view of the same. Fig. 3 is a side elevation of the feed end portion of the machine, which view includes the reel on which the finished wire is wound. Fig. 3 is a detail view showing mechanism for operating a reciprocatory or vibratory guide, by

which the finished wire is guided so as to be wound from end to end of and .in successive layers on the reel. Fig. 3 is a sectional detail showing a spring by which a loose gear or sprocket on shaft 191 is under ordinary circumstances held in rigid connection with said shat't,throngh the medium of which latter the reel is driven. Fig. 4. is a transverse section 'taken on avertical plane indicated by line .4.- 4, Fig. 2, looking toward the delivery end of the machine. Fig. 5 represents on a larger scale a sectional detail taken transversely through a portion of the machine on line 5 5, Fi 2, this view being designed to illustrate a pair of gnidepassages for the wires Fig.

Referring by letter to the several figures of the drawings, in which like letters denote like parts, A indicates a long substantial frame provided with suitable bearings for the oper ative members of the machine.

At the feed end of the machine I arrange a set of straightenirig-rollers, B, for guiding and straightening the wire which is drawn from a conveniently-located spool. These straighteningrollers are arranged in pairs upon a bracket, A, attached to the frame of the machine, the axles. for some of the rollers being set vertically and the axles for the remaining rollers being set horizontally, whereby the wire passing between these said rollers shall be effectively straightened.

A convenient arrangement of these straightening-rollers is illustrated in Fig. 3, in which the vertical rollers are arranged with their axles rising from the bracket, while the horizontal rollers are arranged in two horizontal planes, with the axles for the lower horizontal rollers supported on the bracket and the axles for the upper horizontal rollers secured to a hinged arm, B, which can be swung up so as to allow the wire to be readily introduced between the rollers. The wireis drawn through this set of straightening rollers and fed forward at regular intervals by means of a pair ofintermittingly-rotating feed-wheels, 1 and 2, mounted at the feed end of the machine. These feed-wheels are grooved peripherally for the passage of the wire, and are arranged face to face with a cog or gear-tooth on one wheel en gaging a cog or gear-tooth upon the remain-' ing wheel, so that one wheel shall serve asa means for driving the other.

In order to supply a lubricant to the grooved faces of these wheels, by and between which the wire is fed forward, I provide an oilerwheel, 3, arranged to dip into an oil-reservoir, and also to project into the peripheral groove of the lower feed-wheel, from which latter the oilerwheel is driven by frictional contact. The oiler-wheel is mounted upon an axle, 3, journaled inor on the sides of an oil-reservoir, 3", and is arranged to dip into and take up from a body of lubricant contained in the reservoir a quantity suitable for lubricating the faces of the feedwheels. The upper feedwheel is in the present instance driven from a the lower feed-wheel through the instrumentality of the gearing with which said wheels. are provided, and is mounted upon a short horizontal axle, 4, journaled in bearings 5 5, which are adjustably secured in any suitable way upon vertical rods 6, rising from some se se portion of the mainframe. The feed-wheels are intermittently driven from a horizontal and longitudinally-arranged drivingshaft, 10, which runs along the middle of the machine, substantially from end to end of the latter,

and as a means for thus iuterinittingly actnat ing the feed-wheels the said driving-shaft is provided with a clutch, O, automatically operated at intervals to connect the shaft with a suitable gearing arranged between the shaft and the lower feed;wheel,substantia1ly as follows: The lower feed-wheel is mounted upon a transversely-arranged horizontal axle, '7, provided with a bevel-gear, 8, which gears with a bevelgear, 9, formed or connected with one of the parts 9 of the said clutch.

The operation of this clutch to connect the shaft 10 with the feed-\vheel-aet11atiiig mechanism is effected by a clutch-operating meehanism, which is tripped and allowed to act for such purpose at regular intervals by the action of an advancing portion of the wire during a certain stage of the manipulation of the latter, and which therefore can be more appropriately hereinafter described.

Should the wire be accidentally broken or it become necessary to introduce a new wire into the machine during its operation and while the several parts of the wire in the machine are in various stages of manipulation,it will be found undesirable to continue the operation horizontal plane, the gravity ofthe pawl will cause it to drop into and engage one of the notches in the said wheel, and thereby enable the operator to rotate the shaft 7, and consequently the feed-rolls 1 and 2, so as tofeedthc wire forward without operating the other,

parts of the machine.

By reference to Figs. 1 and 42 it will be seen that when the crank-arm is allowed to swing free in a vertical line the pawl by its gravity will be out of contact with the said wheel. The wire is fed by the teed-wheels forward and over a horizontal table, H, between the rear end of which latter and the feed-wheels the wire is severed at regular in-f tervals by a cutting niechanisn i, D, for which see Figs. 1, 2, 1t), and 11, aud more especially the last two of these said figures. Thefixed jaw of this cutting mechanism consists of some suitable surface atone end of a short.

horizontal passage, 11, for the wire, which said passage runs through an upright, 12, to which the vibratory cutting-jaw 13 is pivoted.

The vibratory cutting-jaw is provided with abent arm, 14, which extends transversely across the machine to a revolving wheel, 15, provided in or. on one of its sides with a camway, 15, engaging a stud or roller carried by a stud on the outer end of the vibratory cutting-arm.

At points beyond the table H are arranged two benders, E E, which operate simultaneously with each other, and which are each adapted during operation to bend the end of, a wire into the form of a hook. These two benders are arranged so that the bender E shall be beyond the bender Ethat is to say, at a point farther along the line of feed, and nearer to the delivery end of the machine-for a purpose which will hereinafter be explained.

At the commencement of the operation of this machine it is necessary to have one por-- tion of a wire running from the supply-reel to the bender F, and a second Wire running from the bender E to and past the delivery, end of the machine, so that after the forward end of one wire and the rear end of theother wire have been bent into hook shape the wire running to the delivery end of the machine can be drawn forward, in order to cause its, hook end to engage the hook end of the other wire, and thus bring the interlocking books up to the coilers, and after the operation of the coilers draw the perfected wire out from them-achine at the delivery end of the latter. At a time prior to such advance of the wire running forward from the bender E the wire I running back from the bender F to the supply-spool is severed by the cutter.

Hereinafter, in referring to the wires, so much of the wire as extends from the supplyspool to the cutter will be termed the feed, wire, and so much of the wire as extends between the cutter and the bender F the back wire, and from the bender E the advance wire, it being understood that during the operation the back wire is severed from the feed-wire and drawn forward by the advance wire, and its place supplied by the feed-wire, which moves forward immediately after the- -back wire is shifted laterally. Assuming the advance wire to have had its rear end bent into hook form by the bender E and the for-v ward end of the back wire to have been bent into a like shape by bender F, and the advance wire to have been drawn forward so that its hook shall engage and thereby draw forward the back wire, it will then become necessary to throw the rear end portion of the back wire, to one side of the line of feed and out of the, way of the reel-wire, which at said juncture in the operation is fed forward. For the purpose of thus pushing the rear end portion of t e back wire out of the way of the feed-wire. I provide a set of kickers, G, (see Figs. 1, 6, and 15,) arranged to push or kick to one side the rear end of the back wire at a time when it is supported upon the horizontal table H, arranged between the. cutter and the first of IIO I a s the two benders. This table, upon which the wire is supported and guided, is secured upon suitable supports, 17 and 17, rising from the main frame, (see Figs. 1 and 5,) and consists, essentially, of an oblong plate provided with transversely-arranged slots 18, in which the kickers G are arranged tooperate. These kickers, preferably three in number, consist of fingers depending, from a horizontal rockshaft, 19, and arranged to pass down through the slots 18 in the table. These kickers normally hang in a vertical plane alongside a vertical wall or abutment, 20, which rises from and runs longitudinally with the table. At a time after the wire running from the reel to the bender F has been severed by the cutter so as to form what I have called a back wire, the kickers are back, or nearly so, against the wall 20, as represented in Fig. 6, and the wire passing along the table is received in notches which are formed in the kickers by cutting away the kickers at their lower ends. The wire fed forward from the reel is maintained in the direct line of feed and in position in front ofthe kickers by means of a keeper, 1, consisting of an angle-plate arranged above the table and connected by several transversely-arranged bars, 21, with a horizontal rockshaft, 22, which is jo'urnaled at its end in brackets 23, attached to some portion of the main frame or some structure rigid thereon as, for example, the piece or pieces which are formed with or secured upon the main frame-in order to provide the wall or abutment 20, described in connection with Fig. 6.

The keeper I is provided with slots 24, for the passage of the kickers G, in order that when the kickers are in their back position, as shown in full lines, they can pass down through the keeper, and also so that when the kickers are swung forward can pass out from the keeper, asindicatedin dotted lines. When the keeper is in its lowestposition, the wire passing forward from the feedwheelslies upon table H in the direct line of feed, and is confined between the keeper and the kickers. After the wire has been severed by the cutter, the rock-shaft 19, carrying the kickers, is turned so as to swing the kickers forward, and thereby push the rear end portion of what is now a back wire out of the way of the feedwire, so as to allow the latter to be fed forward from the reel to its allotted bender, and simultaneously with this operation of the kickers the rock-shaft 22, supporting the keeper 1, is turned so as to raise the keeper from the table, and thereby allow the back wire to be pushed from under it.

The rock-shaft 22, carrying the keeper, is

operated at the proper moments from wheel operated from the lever 25, by which the rockshaft for the keeper is actuated, and for this purpose the rock-shaft carrying the kickers is provided at one end with an arm pivotally connected with the connecting-rod 25.

The rock-shaft carrying the kickers is mounted on bearings 19 on the table, and is turned against a spring-resistance when itis operated to swing the kickers forward. This spring-resistance is provided by a spring, 30, connected with the rock-shaft and one of the bearings for the latter, and arranged so that the rockshaft shall wind up the spring when the rockshaft is turned to cause the kicker to push the back wire to one side of the line of feed. By such means, after the wire running forward from the reel has been reversed, the wire is pushed to one side, and after this the keeper and kickers are returned to their first position, so as to allow the feed-wire to be fed forward between the keeper and the kickers.

As a means for preventing the back wire from springing back or following back thekickers after it has been kicked to one side of the line of feed by the kickers, I provide a set of spring-latches, 31, preferably three in number, which are pivotally connected with the table H or some suitable bracket attached to the latter. These latches extend under the table, and have their catch ends arranged to project up through the slots 18 in the table with the beveled edge of each one of said catch ends nearest the kickers. By this arrangement when the back wire is forced away from the line of feed by the kickers it will ride over and depress the free or catch ends of the latches, which, as'soon as the wire passes, will rise, and hence prevent the wire from spring ing back when the kickers retire or swing back to their normal vertical position. .The back. wire thus kept out and away from the line of feed by the spring-latches is illustrated in dotted lines, Fig. 6, where one of the latches is shown, in which said figure I have also shown in dotted lines the position of the latch when it is depressed. by reason of the wire riding over it, and also the keeper raised from the table and one of the kickers swung out from the keeper. As the delivery-wire is thrown to one side of the line of feed with,

considerable rapidity by the kickers, there wire away from the line of feed, and while the latches are designed to prevent the wire,

from following the retreating kickers, yet it may happen under some circumstances that the wire will as the kickersretreat have a tendency to spring over the latches.

To avoid this movement of the delivery-wire, and also to assist in maintaining the rear end of the back wire in line with the bender E, by which the rear end of the said wire is bent after the'latter has been drawn forward, I provide upon the table H a combined guide and holder, 32, (see especially Fig. 15,) which is raisedfroin the table during the forward movement of the kickers and allowed to drop upon the table and engage the wire after the latter has been thrown or kicked away from the line of feed and back of the catch end of the latches. This combined guide and holder for the wire consists of a bar pivoted at one end to a support, 33, on the table, and provided with a bent arm, 34, which rests upon a pin, 35, extending laterally from the rock-shaft 19, carrying'the kickers. The free end of this bar or holder, by which the rear portion of the back wire is pressed down on the table in line with the first bender, E, is provided with one or more grooves, 36, so as to prevent the wire from slipping laterally from under the holder. WVhen the kickers are swung forward, the holder is lifted from the table by means of the pin on the rock-shaft engaging under its arnr 34, and as soon as the wire has been pushed under the holder and the rock-shaftcommences to turn so as to swing back the'kickcm, the holder is of course allowed to descend and rest upon the wire. As the wire is held in this position on the table simply by the weight of the holder 32, it will be evident that while the rear end of the back wire is pre- Vented from a lateral movement by reason of the grooved or corrugated under side of the holder, thelatter will not interfere with the wire being drawn forward so as to bring the rear end of the said wire up to its allotted bender E. At a time after the rear end por-. tion of the back wire has been thus pushed out of the way of the feed-wire the reel-wire is fed forward to the bender F, and the back wire is drawn forward so as to bring its end up to the bender E, the back wire lying upon the table at one side of the keeper 1. and the feedwire being fed forward under the said keeper by the feed-wheels.

In order to stop the said feed wheels, so as V to arrest the forward feed of the feed-wire at a moment when its end has been brought into position under the bender F, l provide in the line of said wire at a point beyond said bender atrip, K, which, when struck and operated by the end of the advancing feed-wire; releases a mechanism by which the clutch Ois actuated, and the transmission of motion from shaft 10 to the feed-wheels thereby arrested. The trip K, which is best shown in Fig. 18, is in the nature of a beltcrank lever pivoted bya pin, 37, to a two-part bracket, 38,-which is secured to the main frame of the machiue. This bellcrank lever has its upwardly-extemling arm 39 adapted to be acted upon by the end of the v advancing teed-wire; or, if preferred, its said arm can be provided with a plate, 41, against which the wire shall strike. The upper arm of this trip is normally maintained in the line of feed and in position to be struck by the end.

bell-crank is arranged the forward and free end of a lever, 43, (see also Figs. 17 and 18,) which said lever 43 is arranged about midway of and transversely to the length of the machine. This lever 43 is pivoted by a pin, 44, at what maybe termed its rear end to some stationary part of the main frame. A rod or pitman, 45, made extensible in any ordinary wayas, for example, by forming it of two parts having their opposing ends fitted in an internally-screw-threaded collar, 46is pivotally connected at one end with the vibratory lever 43 and at its opposite end pivotally connected with a vibratory clutch-shifter, by

which one part of the clutch O is operated. This clutch-shifter, which is best illustrated in Fig. 10, consists of an upright frame, 47,

sists simply of a hub, 49, arranged to slide upon shaft 10, and provided with a wheel or.

flange, 50, adapted to engage with or to be disengaged from the wheel 9, said hub 49 being carried by and arranged to revolvein a collar,

51, which is pivoted in the frame 47. It will be understood that the hub and the wheel 49 and 50 revolve with shaft 10, and can in practice be feathered thereon, so as to be capable of being shifted toward or away from wheel 9; or, if preferred, the hub 50 can be loosely arranged on shaft 10 and engaged by pins projecti'ng from one end of a collar, 10, which is rigid upon the shaft 10, in which case the pin will enter holes formed in one end of hub 49, whereby,while the latter shall rotate with the shaft 10, it can also be susceptible of a sliding movement thereon It is also understood that the clutch preferably operates upon theprinciple of an ordinary friction-clutch,which can be attained by concaving one side of wheel'9 and beveling wheel 50 at one side or end,so that when thelatter is forced into the side of wheel 9 the said wheel shall be driven by reason'of the frictional contact between the two wheels. The part 50 of the clutch is thrown into gear or clutch with the part by means of pitman 45, which throws part 50 forward and against some spring or weight resistanceas, for ex ample, a weight, 52, suspended by a link, 53, from a horizontal arm, 54, extending from one side ofthe vibratory frame or shifter 47-which said weight or spring, as the case may be,tends to throw the sliding part 50 away from the remaining part 9 of the clutch, and hence out of frictional contact with the same as soon as the clutch-operating mechanism has been released. The lever 43 is operated at the proper moment, so as to throw the rotary and sliding member of the clutch into engagement with the remaining member 9 thereof, which is loosely arranged upon the driving-shaft, whereby motion shall be transmitted from the drivingshaft to the feed-wheels for the purpose of advancing the feed-wire. Asa means of thus actuating the lever 43, the rotary shaft 16 is provided with a cam, 54:, which, during the rotation of said shaft, is brought into engagement with roller 55, carried by an upright vibratory yoke-shaped frame, 56, which is pivoted or hinged upon the main frame of the machine and connected by a rod, 57, with the lever 43. The action of this cam is to swing the frame 46 toward the clutch, and hence, through the medium of lever 43 and the pitmen or connecting-rods 57 and 45, throw one part of the clutch forward and into gear with the remaining portion of the clutch.

In order to maintain the two parts of the clutch in gear with each other until the feed wire has been advanced to the required extent, the clutch mechanism is looked as soon as the two parts of the clutch are in gear with each other, and atthe proper moment released by the action of the end of the feedwire against the trip K. For this purpose I provide under the lever 43 a stationary bar, 58, provided with a notch, 59, in which lever 43 drops after it has been drawn forward or toward the clutch by the action of the swing' ing frame 56. So long as lever 43 rests in this notch the two parts of the clutch will be maintained in gear with each other, and the feedwire will be fed forward; but when the upper end of trip K is struck by the end of the advancing feed-wire, the upper arm of said trip will be swung back, and consequently its lower arm raised, so as to lift lever 43 out of the notch 59, at which instant the weight 52 will act to throw back the clutch mechanism, and hence swing thelever 43 back of thenotch 59, and thereby cause the feed to be automatically stopped. It will be understood that at the moment when lever 43 is lifted and released from the notch and the clutch, and clutch mechanism thrown back by the weight or spring, the cam 54 on shaft lli will be out of the way of roller 55 on frame 56, so as to allow the latter to swing back with the backward shift of the clutch-actuating mechanism, and that the said frame will swing back so as to again bring its roller 55 in the path of the said cam. After the forward feed of the feedwire has been stopped and severed by the cutter, the forward end of this severed wire, which I now term a back wire, is lifted up to the bender F by the upwardly-bent end of a pivoted spring-controlled lever, 60, which is shown partly in full and partlyin dotted lines in Fig. 18. This lever, which I denominate the wirelifter, is pivoted at one end in a space within the pedestal 17, and has its free upturned end arranged to rise directly under the forward end of a back wire at the proper moment. The wire-lifter is swung upwardly by one end of a vibratory lever, 61, arranged transversely in the machine and pivoted at 62 to some stationary part of the main frame. Thislever 61 is turned about its pivot at the proper moment for swinging up the wire-lifter 60 by means of a cam, 63, arranged upon one side ofa wheel, 64, and adapted to act during the revolution of said wheel against a roller, 65, carried upon one end of the vibratory lever 61.

The cam 63 is illustrated in dotted lines, Fig. 16, and the wheel which is provided with said camis secured upon the horizontal rotary shaft 16.

To insure the depression of the wire-lifter after lever 61 has been released from the cam 63', I provide a spring, 60, against which the wire-lifter is raised.

The two benders E and F are each of the same construction, or substantially so, and are each adapted to bend an end of one of the wires into the form of a hook, (shown in Figs. 30 and 31,) these said benders being so arranged that the bender E shall bend the rear end of the advance wire into a hook lying in a horizontal plane, so that when the advance wire is drawn forward,after these hooks have been thus formed, the hook of the advance wire shall engage with the hook of the back wire, as illustrated in Fig. 33.

The construction of these benders will be best understood by referring to Figs. 12 and 13, in which the bender F is shown inside and end views. It will be seen that this bender comprises a cylindrical body, 66, enlarged laterally at one end, as at 67, and provided upon its faceend with a finger, 68, and a small roller, 69, between which said finger 68 and roller the wire is received, so as to be bent into hook form when a partial revolution is given to the bender, as illustrated by dotted lines in said Fig. 13, in which said figure the feed-wire x is also shown in full lines passing between the roller and the bender.

The wire-lifter 60 (illustrated in Fig. 18) is designed to lift the end of one of the wires into proper position between the finger and the roller on bender F after the forward feed of the reel -wire has been stopped and the same severed by the cutter. The wire thus upheld by the wire-lifter is bent into book form by the bender F, which makes a partial rotation to thus bend the wire and then turns back to its first position.

The bender F is operated by a horizontallysliding rack-bar, 7 0, arranged transversely to the length ofthe machine, and engagingagear, 71, which is formed with or secured upon the cylindrical body 66 of the said bender. This rack-bar slides through a case, 72, mounted upon the pedestal 17, and a suitable bearing,

73, on a rear pedestal, 74, and is reciprocated at the proper moment from wheel 61 through the medium of an upright vibratory lever, 75.

(Illustrated in Fig. 17 This lever is pivoted at its lower end to some portion of the main frame, and at its upper end is provided with a notch in which a stud or collar, 76, upon the rack-bar engages.

The lever 75 is provided on one side with a stud or projection, 77, as shown in dotted lines, and the wheel 64: is provided upon one of its sides with a stud, 78, which latter during the revolution of the wheel comes in contact with the stud on the lever, and thereby swings the lever forward.

The rack-bar is provided with adownwardly-projecting stud, 79, and the wheel is provided on its periphery with a tooth formed by recessing the wheel, as at 80, whereby after the rack-bar has been moved forward by a forward swing of the lever 75 the stud on the rack-bar shall during the revolution of wheel 64 be engaged by said peripheral tooth of the latter, and hence the rack-bar be moved back into the position shown in Fig. 17. This stud and tooth on the wheel 61 are so arranged as to reciprocate the rack-bar at the proper moments, and hence effect the required partial revolution of the bender F successively in reverse Cirections for the purpose of bending the end of the back wire into hook shape and then returning the bender into its first position ready for the next wire.

" The bender F is arranged to turn about a vertical axis, so that during its partial forward rotation it shall bend the forward end of Lil - this latter bender it will bend the rear end of the advance wire in ahook on a vertical plane, whereby when the advance wire thus bent is drawn forward the two wires shall have the position relatively to each other as shown in Fig. 30, in which x denotes the forward end of the back wire bent into a hook on a horizontal plane, andy the rear end of the advance Wire bent into a hook on aVertic-al plane, so as to be capable of interlocking with the hook of the back wire.

The bar 81 (illustrated in Fig. 16) is provided for the purpose of steadying and keep ing the forward end of the back wire in position to be bent after said wire has been raised by the wirelifter 60, and also for bringing and maintaining said wire afterit has been bent into position to be engaged by the bent end of the advance wire at a time when the latter is drawn forward. This bar is reciprocated longitudinally at the proper moment, and is arranged to be capable of a limited swing in a vertical plane, so that at the required time its forward free end can rise and fall simultaneously with the up-and-down movement of the wire-lifter 60, by which it is raised. To such end the intermittiugly-reciprocating bar 81 passes through a horizontal passage, 82, formed through the case 72, and shown in Fig. 17, said passage being of a height sufficient to allow a vertical play on the part of the bar, which is normally kept down in its lowest position in said passage by means of some suitably-arranged spring, 83, which said spring can be conveniently attached to the top wall of passage 82 and adapted to bear upon the bar 81.

The horizontal bar 81, which is arranged transversely to theline of feed, is widened and flattened at its forward end, as shown, and is provided on its under side at said end with a notch, 84, adapted to allow the hooks of the feed and delivery wires, when interlocked with each other, to stand therein, as illustrated in Fig. 16. This bar is also provided at its forward end portion with a horizontal slot, 85, commencing at a point at the side of the notch 84, and designed to receive the forward end of the back wire as the latter is bent into hook shape,whereby after the hook has been formed its end resting in the lower horizontal wall of said slot shall be supported, and the hook thereby maintained in a horizontal plane ready to be engaged by the hook-shaped end of the advance wire when the latter is drawn forward.

As a means for holding down the hook shaped forward end of the back wire and for assisting in maintaining the hook in a hori zontal plane as long as may be necessary, the bar 81 is also provided at its forward end with' a springlatch, 86, consisting of a bent pin having its vertical portion arranged to turn in the bar 81, and its lower horizontal portion arranged to cross notch 84in the widened end of said bar. The lower horizontal portion of this latchis normally held across notch 84and against one of the vertical sides of bar 81 by means of a spring, 87, in which position the latch will lie above the hookshaped end of the wire 00 after the same has been bent by the bender F. Thelatch, however, is susceptible of being swung out and away from the notch in order to allow the interlocking hooks of the wires to be drawn forward to the coilers, hereinafter to be described, for which purpose the hook-shaped end of the advance wire y, when the interlocking-wires are drawn forward from the position shown in Fig. 16, will strike and swing the latch out of the way.

Upon the pedestal is arranged an angleplate, 60, having a horizontal arm portion, 60, Fig. 14, extending over the path of the wire passing to bender F. When the wire is. lifted up to said bender by the lifter 60, the wire when in positionto be bent by the same will be held between the wire-litter 60, and the arm 60 of plate 60", which constitutes a rigid jaw, while, as will be seen, the lifter constitutes a movable jaw, which, while acting on the wire a little in advance of the rigid jaw, serves to hold the wire while the free end of the wire is being bent by the bender. The bar 81 is lifted, simultaneously with the wire by reason of the wire which is raised by lifter 60 pressing up against the jaw 86. The bar 81 is pivotall y connected atits rear
